Why choose an unmedicated birth?

I’m a FTM, currently 29 weeks and I keep being asked about my birth plan. I’m doing my research to figure it out, but see so many people are opting for an unmedicated birth. It’s never crossed my mind to skip meds so I’m curious why others want to do it?

Edit: thanks for all the responses, I so appreciate it! 🙏🩷 after reading this I’m going to go the birth preferences route (rather than a plan) and know what I’d like to do but be ready to change dependent on how labour progresses.
